I don't agree. With 200 kh/s, (achievable with GPU mining), you would expect to hit a block around once every 5 days (at least according to the litecoin calculator). If 10 people do that, it would take 12 hours per block.
If you have a nVidia graphics card, then you should search for cuda miner.
The command line is:
cudaminer.exe -o localhost:9223 -O
You also need to add this to your craftcoin.conf file
rpcpassword=
rpcallow=127.0.0.1
rpcport=9223
